When you need a reliable 4-season sleeping bag for the Sierra Nevada or Rocky Mountains, the Antelope is built for cold nights, shoulder-season storms, and backcountry conditions where warmth matters most.
Designed for backpacking, thru hiking, and alpine camping, it delivers serious cold-weather performance without unnecessary weight.
Warmth & Insulation
Filled with 26 oz. of high-loft 850+ fill power goose down, the Antelope achieves 7" of loft and a 5°F temperature rating, making it ideal for early spring through late fall trips in the mountains.
Comfort & Fit
A 62" shoulder girth provides a roomy, comfortable fit for side sleepers and those who don’t want to feel restricted after long miles on trail.
Draft Protection System
Built to hold heat in tough conditions, it features:
- Full 3D down-filled draft collar
- Robust draft tube along the zipper
- Secure neck seal to prevent heat loss on cold nights
Shell Fabric & Weather Resistance
The MicroLite XP™ shell balances durability, weather resistance, and breathability, helping manage moisture while protecting against wind and light exposure. Even the down collar uses MicroLite XP™ fabric for consistent thermal efficiency.
Weight & Use Case
At just 2 lbs. 7 oz., the Antelope is one of the most capable sub-3-season expedition down bags in its class—ideal for hikers who prioritize warmth in real mountain conditions.
Also available in 5’6” length for a more precise fit.
